I currently use setcpu and under advanced when i try to change the sample rate it goes haywire and stops then set cpu force closes tried different settings even default doesnt work tried different kernels to.
Any help would be great or if i can manually set the sample rate ?
also nice levels battery save levels up threshold or down threshold
Everything on the advanced list

Without setcpu or pimp installed, if I just set the max of 1000 and min of 216 in the cm7 performance settings menu to restore on boot, will I get the same effect (the only governor setting that will stick is "null")?
Or is it still beneficial to use setcpu to set a screen-off profile?
And the screen-off profile, should the min and max be the same? 216/216? Or is it better to stagger it a little, like 216/312?
I ended up still using setcpu. The built in CPU settings did not work for me.

No, because this allows the governor to change the CPU anywhere between 216 and 1000. This is the default; unrooted stock has it like this.

I keep it 216/216 then allow an in-call profile that goes up to 312 in case when I'm calling someone and the screen is off it needs a bit more juice.
So basically, if I have setcpu installed, but I leave profiles "DISABLED", and leave the sliders alone, then I'm getting no different result from stock? The governor will decide to use the cpu at whatever frequency between 216 and 1000 that it needs at the time?

The Tegra 2 chipset doesn't allow you to change the governor settings. So to answer your question, yes the CPU chooses what frequency it needs depending on load.
anybody got any tutorials on getting set cpu to work on the sensation? what do i select at the first boot of set cpu where i have many phone models to choose from as i cant see the sensation
I too would love some ideas on settings
When I used it on the HTC HD2 the recommended settings was to have the scaling set to "On Demand" and the box checked for Set on Boot. max 1000, min 216. The second item you want to do is click on the profiles tab and add Screen Off and set the min and max to 216 each and set scaling to "On Demand". make sure you check the box "Enable". Also make sure you grant permission in SuperUser. These setting work great on the Sensation from what I have seen.
it seems that there is a new OC Deamon on its way:

should be default OC-D in AR soon!
Noticed something interesting. Using ondemand governor, when the phone boots up, the "sampling rate" reads 50000 in SetCPU. As long as the screen doesn't go off, it remains at 50000. But after a screen off and then on, the sampling rate becomes 10000, and stays this way. Is this normal that the governor changes its parameters like that?
Innitially I thought it could be a SetCPU problem so I tried Trickster Mod. Same thing happened.
The screen off could either be a screen time-out or using a wedget to turn off the screen. They all cause the sampling rate change from 50000 to 10000. This happens on both the stock MB1 kernel and the Zeus V5 kernel. Didn't tried this on other kernels so I don't know. Neither do I know if other governors change their parameter as well,
Anyone with the knowledge can explain this? Or it's supposed to work this way?
So i set my max cpu freq to be 1728. And then the temperature throttle's 3 phases to be different clock speeds of 1728, 1267 and 1036. So when the temp hits a certain temp it will throttle the cpu down to the latter two. But then when the temp decreases to the values i set, then it should go back to the desired max speed i want which is 1728 however this is not the case. I often see it stuck at 1267 even though the temperature is well below the temp settings i set. It even gets stuck at 1036 at times. Any ideas how to get it to change back appropriately? I only use synapse to configure the settings. I'm also on mahdi rom which has that performance settings which I don't know if that is causing any conflicts the settings that i set in synapse.

It is a bug in the thermal driver code of the kernel you are using.
Report to the dev with proper logs, and readjust the clock speeds in Synapse or reboot.
I am trying to find what parameter miui uses for refresh rate adaptiveness. Maybe a developer can find or already know. I changed surface_flinger touch and idle timer props from 1100ms to 250ms bu nothing changed. Strangely, UI lowers the refresh rate after 3 second anyway. It doesn't even use the default prop values.
